If emf induced in a coil is 2V by changing the current in it from 8 A to 6 A in `2 xx 10^(3)` s . Then , the coefficient of self -induction is

An emf of 2 V is induced in a coil when current in it is changed from 0 A to 10 A in 0-40 sec. Find the coefficient of self-inductance of the coil.

An e.m.f. of 250 muV is induced in a coil, when current in it changes from 10 A to 6 A in 0.4 s. What is the self inductance of the coil?

When the current in a coil changes from 8A to 2A in 3xx10^(-2)s , th eemf induced in the coil is 2V . The self-induced of coil in mH
